I think, most people already knew about microwave. Yes you are right, this is a thing that is used for heating or cooking something. On normal basis, its main function is as kitchen appliance. I bet that function is not something unusual for all of you, but do you know how a microwaves work?

A microwave oven, or a microwave, uses microwave radiation to heat water and other polarized molecules within the food.A microwave oven works by passing non-ionizing microwave radiation, usually at a frequency of 2.45 gigahertz (GHz)—a wavelength of 122 millimetres (4.80 in)—through the food. Microwave radiation is between common radio and infrared frequencies. Water, fat, and other substances in the food absorb energy from the microwaves in a process called dielectric heating. Many molecules (such as those of water) are electric dipoles, meaning that they have a positive charge at one end and a negative charge at the other, and therefore rotate as they try to align themselves with the alternating electric field of the microwaves. This molecular movement represents heat which is then dispersed as the rotating molecules hit other molecules and put them into motion

To produce the heat by using the microwave radiation, a microwave need to have a microwaves generator. Microwave generator is a device in the microwave that produce microwave and covert that radiation to heat. The microwave generator vary among one another, depends on the type of microwave used : standard or industrial microwaves generator. Industrial microwave generators provide a level of efficiency that cannot be reached through more conventional heat generation methods, the industrial microwave uses Thermex Thermatron technology to reached that level of efficiency. Because the need of industries vary one among the others, there are several type of thermex thermatron,which are 6kW to 30kW generators operating at 2450MHz and 75 to 100kW generators operating at 915 or 896 MHz. I suggest you to visit Thermex Thermatron website for more detail information about microwave generators.
